Just visit this chaotic area around Misono building. There are some pathes with various bars run by independent owners alongside. The best way to make local Osakan friends is to jump in this area and go bar-hopping. Also good to dig the osaka underground cultural scene.

Around this area, you can easily find 100yen-draft beer for weekday lunchtime. Nice activity to start a day with! Be careful not to drink much as there are lots to see and experience during travel.
